One-Finger Stopping Power. Total Control for Heavy E-Bikes.

Riding a heavy OUXI V8 fat bike at high speeds with standard factory mechanical brakes is a workout for your hands and a risk to your safety. Mechanical cables stretch, brake pads wear unevenly, and stopping requires pulling the levers with all your strength. Transform your riding experience with this Complete Hydraulic Brake Upgrade Kit.

Engineered for the extreme weight and speed of electric fat bikes, this dual-piston hydraulic system delivers immediate, buttery-smooth stopping power with just the pull of a single finger. The sealed mineral oil system means you never have to adjust cable tension again—the brake pads auto-adjust as they wear. Complete with built-in electronic power cut-off sensors, this kit immediately kills motor power the millisecond you touch the brakes, ensuring maximum safety in emergency situations.
